Although I am a Federal Firearms Licensed Manufacturer, I am not a trained gunsmith. I can build firearms for you, and I can modify firearms for you. When it comes to traditional gunsmithing services like threading a barrel or glass bedding an action, I can recommend reputable gunsmiths. I can also sub-out gunsmithing services for you to incorporate into any custom build. When I do that, you will pay what I pay for the smithing, I don’t mark that up.
